Mn'rALLIc, WALL consrnucrrioni Application filed March 26, 192 Serial Nd. 97,732.

My present invention relates to the art of building and more particularly to the construction of walls, ceilings and floors, and it has for its object toprovide an improved metallic support composed of sheet material that will be strong and durable and to which plaster, cement or similar material may be applied as a facingand securely nterlock therewith. To these and other ends the invention resides in certain improvements and combinations of partsall as will be hereinafter more fully described, the novel features being pointed out in the claims the end of the specification.

In the drawings:

Figure 1 is a top or end view of a wall,-

ceiling or floor constructed in accordance with and illustrating one embodiment of my invention; g

Figure 2 is an elevation of the metallic support before the plaster or concrete is applied thereto and e Figure 3 is a fragmentary plan view of the prepared blank from which the metal-' lic support is formed.

Similar reference numeralsthroughout the several views indicate the same parts.

My invention is not essentially in the nature of a concrete reinforcement but, as before stated, is a sheet metal wall, ceiling and floor construction to which plaster or concrete is applied, the supporting element being the metal and not the concrete or plaster. This supporting element consists of a strip of sheet metal of suitable length and width shown in the blank in Figure 3. At intervals it is provided with rows of perforations 1 and preferably these perforations are formed not by cutting out the metal altogether but by cutting'it on three sides and bending it inwardly on the fourth as indicated at 2 so that an inwardl 1 projecting ear is formed in each instance for the purposes hereinafter described.

After these perforations are made along parallel lines at a distance apart, the sheet is folded in a multiplicity of loops 3 as indicated in Figure 1.' The exact nature of these loops is difficult to describe'and is best or semi-circular bend is made and then a reverse bend of the same nature and so on back and forth until each. side of the metallic supporting wall presents a semi-cylindrica1 series of bends as shown. in Figures 1 and 2 with their sides touching or tangential to shown in Figure 1. A substantially circular each other. This provides either a vertical or a horizontal. support of maxlmum strength. I

Additionally to the perforations 1 the sheet shown in Figure 3 is provided at intervals with perforations 4? which, when the sheet is bent up into the form shown in Figures 1 and 2, are adapted to accommodate a, bolt 5 terminating in nuts 6 and suitable washers 7 that permit of the convolutions of the sheet being drawn together so that their contacting sides are'held in engagement with each other and-prevented from separating.

The plaster, concrete or other, facing is indicatedat 8. It is applied in the manner shown in Figure 1 to the surfaces displayed in Figure 2. It does not enter between the loops or convolutions 3 but flows into the perforations 1 thereof as shown at 9 in Figure 1 being locked by its engagement with the ears 2 that are bent inwardly from the perforations.

In this way, the convolutions of the metal sheet, weaving back and forth as they do in semi-cylindrical form, provide the maximum supporting strength whether the sheet is disposed vertically Or horizontally and the bolt 5 holds these parts in this relationship while the plaster or concrete 8 is being applied to make the surface or facing. At the same, time such plaster, concrete or other plastic substance is caused to adhere to the metal support by flowing in through the openings 1 that are lndrical surfaces and by being locked therewith through flowing around and about the ears 2 that are formed in connection with the openings 1.

A wall support of this character is cheap ly manufactured and may be advantageously used for ceilings, walls or floors. The metallic part has great strength and at the same time acts as a metallic lathing for binding on the plaster or other plastic surface.

I claim as my invention:

1. A wall construction embodying an integral sheet metal support folded back and forth into a succession of identical,-directionally reversed and semi-cylindrical loops the ad acent surfaces of which are in intimate tionally reversedand semi-cylindrical loops exposed on the outer cy the adjacent surfaces of which are in intimate contact and are provided with perforar tions adapted to receive and cause to be interlocked therewith a plaster or similar plas- 5 tic surfacing material.

3. A Wall construction embodying a sheet metal support folded back and forth into a succession of semi-cylindrical,loops the adjacent surfaces of which are in intimate contact and i are provided with perforations adapted to receive and cause to be interlocked therewith a plaster or similar plastic surfacing material; and a bolt extending transversely through said loops to maintain them in such contact with each other.
